IC 5146 Cocoon Nebula #4

Next up from Okie-Tex -- IC 5146, the Cocoon Nebula!
This is another one from the enormous Nikon 400mm f/2.8 I had the pleasure of borrowing, with the QHY533M I'm testing for QHY.

The Cocoon is mostly an emission nebula with some reflection nebula (that I wasn't able to pull out as much as I'd hoped) in the blue around the edge of the red. There's also a large dark nebula, Barnard 168, surrounding the Cocoon and extending like a massive finger downwards. It's located in the star-studded constellation Cygnus. Being an emission nebula, there's a ton of hydrogen gas that is the source of newborn stars in the nebula.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
